Cela fait maintenant 72H que je cherche sans trouver merci d'avance a l'ame charitable qui me viendras en aide ( fonctionne sous 32bits - ces erreurs surviene sur une plateforme 64bits.).

Les messages sont clairs non?

- Tu utilises le mauvais pointeur pour certains cas
- Tu ne peux pas faire 'i o o o o' pour un case
- Tu dois faire ton arithmétique sur les pointeurs maintenant avec 64 bits...

A mon avis tu auras d'autres soucis après avoir résolu ceux-là

Salut,

De manière générale, les avertissements te signalent que tu transmet un pointeur sur une valeur de type size_t (typiquement, on peut considérer qu'il s'agit d'un unsigned long) alors que la fonction s'attend à recevoir un pointeur sur un élément de type socklen_t.

Il faudrait donc essayer de vérifier quel type de donnée est associé à socklen_t, car il se peut que ce soit un simple /* unsigned */ int ou un... /* unsigned*/ long long. Il y aurait donc deux solutions possibles : soit, tu risque une "perte de données" (un int, signé ou non ne permet que la représentation d'un intervalle de valeur bien plus petit qu'un long), soit tu n'arriveras jamais à utiliser toutes les "valeurs représentables" par un socklen_t, ce qui -- en définitive -- s'avèrerait être "le moindre mal"

Dans le cas présent, si ton code compile en mode 32 bits sans avertissement mais pas en mode 64 bits, j'aurais sans doute tendance à pencher pour le le fait que (pour une raison ou une autre) tu utilises les en-tête spécifiques au mode 32 lors de ta tentative de compilation en mode 32 bits; du moins, en ce qui concerne l'alias de type socklen_t.

Aussi bizare que cela puisse paraitre, je ne serais pas étonné s'il y avait un symbole préprocesseur susceptible d'être défini afin de corriger le problème. Quelque chose (à dénicher dans le fichier d'en-tête) qui pourrait ressembler à

Code :

#if defined(USE_32BITS) // c'est peut être pas ce symbole là, précisément 
    typedef socklent_t  unsigned int;
#if defined(USE_64BITS)
    typedef socklen_t unsingend long; // c'est peut être pas ce symbole là non plus
#endif

Tout ce que tu aurais donc à faire afin de corriger le problème serait d'ajouter un -DLE_SYMBOLE_VOULU_POUR_64BITS à tes options de compilation afin de corriger le problème

Ceci étant dit, il faut savoir que les socket "linux" et les sockets "windows" fonctionnent différemment, et que leur utilisation peut imposer de lourdes restrictions en termes de portabilité. Ainsi, si tu en venais un jour à décider de porter ton application sous windows, tu te trouverais sans doute face à l'obligation de truffer ton code de

Code :

#ifdefined (__WIN32)
    /* code spécifique à windows */
#elif defined(LINUX)
   /* code spécifique à linux
#endif

(bon, d'accord, il y a d'autres possibilités, et celle-ci est sans doute la plus vilaine de toutes )

De plus, il faut savoir que les bibliothèques issues du C posent un tas de problème à l'utilisation en C++, non pas parce qu'elles sont "incompatibles", mais "simplement" parce que C et C++ sont devenus des langages totalement différents avec le temps, ce qui occasionne certains "point de friction" entre les langages.

Par chance, il existe des bibliothèques (écrites en C++) qui offrent une réponse correcte à tous les problèmes que je viens de citer, dont, entre autres, boost::asio, dont l'utilisation pourrait t'éviter bien des cheveux blancs.
